Robert Ettinger, pioneer of the cryonics movement that advocates freezing the dead in the hope medical technology will enable them to live again some day, has died. He was 92.
The Cryonics Institute in the Detroit suburb of Clinton Township said Mr Ettinger died on Saturday and was promptly frozen.
Son David Ettinger said his father's health was failing for some time.
Mr Ettinger senior first proposed storing dead bodies at low temperatures to await future revival in a 1964 book. He continued promoting the idea for decades in writing and public appearances.
He founded the Cryonics Institute in 1976. He is the 106th person whose body is stored at the institute at minus 321F (minus 196C) in liquid nitrogen.
David Ettinger said his father was a "reluctant prophet" who was not bothered by people ridiculing his ideas.
